Actually, no. The behaviour you're seeing is the way externals have
been designed (ie, it's not a bug): they have been designed to point
to other repositories. In secondary repositories, the revision number
from the primary repository has no meaning.
For example, if you had primary repository A at revision 12000 and
secondary repository at revision 500 (a young project), you'd have a
lot of problems when backdating the main repository tree to r11999,
because that revision doesn't in repository B.
What you're experiencing is the fallout from using externals for what
they haven't been designed for.
What you *could* do however is use the switch command to emulate
intra-repository links: Create empty directories where you have your
module dependencies and 'svn switch' those directories to the parts of
the tree where your deps live. (You could use a wrapper to do that for
you.)
If you then backdate (update with a historical revision) the tree,
you'll also see the modules be updated.
HTH,
